By placing the handle of the shifting-lever directly over the pin the terminals of said lever do not operate either of the pawls, so that both are thrown into engagement, and hence I form a rigid socket-wrench.

From the foregoing description it will be seen that I provide a simple economic construction of wrench adapted to be used upon various-sized nuts and to be operated either in applying or removing the same in obscure or intricate positions, said wrench requiring but a small space in which to operate, and that I have provided a simple device readily accessible to the operator, by which either or both of the pawls may be thrown into engage ment or either withdrawn.

Having described my invention, what I claim is- 1. In a wrench, the combination, with the stock or handle terminating at its front end in a circular head or ring provided near one side with an internal annular flange, a hub mounted for revolvingin the flange and provided above the same with a ratchet-wheel, and opposite circular plates secured to the hub and overlapping the faces of the head of the wrench, of a rectangular socket removably inserted in a correspondingly-shaped opening formed in the hub, said socket being provided with a flange at one end taking into a recess formed in one of the plates and at its opposite end provided at diagonally-opposite corners with grooves, and the locking-key formed offspring-wire and consisting of a handle and diverging terminals inwardly bent at their ends and sprung removably into position in the grooves, substantially as specified.

2. In a wrench, the combination, with the handle terminating at one end in a circular head or ring, a ratchet-wheel mounted for rotation in said ring, and means for securing the same, of a pair of pawls pivoted in recesses formed at the juncture of theringand handle, the forward ends of the pawls being inwardly disposed to engage with the teeth of the ratchet, springs interposed between the tails of the pawls and the bottoms of the recesses, a T-shaped lever pivoted upon the handle and having its opposite branches depending to bear upon said pawls, and a locking-pin projecting from therhandle in rear of the pivot of the lever and to either side of which said lever is adapted to be thrown, substantially as specified.

In testimony that I claim the foregoing as my own I have hereto affixed my signature in presence of two witnesses.

ANDREW IIULLINGER.
